      • toI420

        public VideoFrame.I420Buffer toI420()
        Description copied from interface: VideoFrame.Buffer
        Returns a memory-backed frame in I420 format. If the pixel data is in another format, a conversion will take place. All implementations must provide a fallback to I420 for compatibility with e.g. the internal WebRTC software encoders.

      • release

        public void release()
        Description copied from interface: RefCounted
